Title:
Stairseal
Kind Code:
A1


Abstract:
A sheet metal enclosure containing a thickness of Styrofoam Insulating material designed to slide over the plywood panel on attic stairways. A rubber seal is placed on the perimeter of the back side of the panel creating a seal between the living area and attic space reducing air transfer between the two spaces. The Styrofoam provides an amount of insulation reducing temperature transfer between the two spaces. The sheet metal panel provides for the containment of the insulating material and mounting surface for the rubber seal and reduces warping of the attic stairway plywood panel because it is held rigid within the confines of the metal enclosure containing the Styrofoam. The closure springs on the attic stairway provide the tension to hold the stairway closed and create a tight seal.

Claims:

What is claimed:



1. The rubber seal prevents air transfer between living areas and attic space.

2. The Styrofoam provides insulation against thermal transfer between the living and attic space.

3. The steel panel provides for containment of the insulation, mounting of the rubber seal and strengthens the plywood access panel preventing warping while sealing and insulating the attic stairway opening thereby reducing air and temperature transfer leading to reduced utility bills and power consumption.

Description:

FIELD OF THE INVENTION

[0001] The invention directly relates to folding attic stairways insulating and sealing as the prevent heating and cooling losses thereby reducing utility usage and expense.

BACKGROUND OF THE INVENTION

[0002] Attic stairways are often placed in homes allowing access to a buildings attic space. While the attic is normally heavily insulated to prevent heating and cooling losses, the plywood doorway on an attic stairway is not insulated or sealed in the closed position, leading to higher energy usage and costs.

[0003] What is Claimed.

[0004] Stairseal is a sheet metal panel containing within its confines an insulating panel combined with rubber seals placed along the perimeter of the mounting flanges as to form a seal on the attic doorway when in the closed position, a self adhesive foam seal is adhered to the stairseal panel on the hinge end of the attic stairway to further reduce air transfer. Preformed mounting flanges on the back or non-exposed side of the stairseal allow the unit to easily slide over the existing attic stairway plywood door and be attached with self drilling screws. Within minutes and energy waster is converted into an energy saver while improving appearance and reducing maintenance.

[0005] Legend.

[0006] 1. Preformed sheet metal“C” panel.

[0007] 2. Panel of insulating material placed within the confines of the preformed “C” Panel 1

[0008] 3. Preformed “c” end cap for non-hinge end of Stairseal panel.

[0009] 4. Sheet metal angle (90 deg) made to height of ¼ in smaller than the inside depth of the Stairseal panel , this allows the attic stairway plywood door panel to slide into the Stairseal panel from only one end, referred to as the hinge end

[0010] 5 Self adhesive foam seal to be attached to 4 to reduce air transfer at the hinge area on the attic stairway.

[0011] 6, 7, 8 Self adhesive rubber “p” seal for attachment to preformed mounting flanges on 1 and 3

[0012] 9,10,11,12, Self drilling sheet metal screws for attaching 3 and 4 to the ends of 1

[0013] 13,14,15,16, Self drilling sheet metal screws for attaching finished Stairseal unit to existing attic stairway plywood door panel.

[0014] 17 Rubber grommet used to protect pull down rope from hole drilled in 1.
